I am having trouble installing octave 3.8.1 under Red Hat EL6.5. The trouble is, configure can't find pcre. pcre is installed, and pcre-config is on the path. I can run it by hand, and it seems to do the right things. But when I run ./configure, it winds up with:
checking pcre.h usability... no
checking pcre.h presence... no
checking for pcre.h... no
checking pcre/pcre.h usability... no
checking pcre/pcre.h presence... no
checking for pcre/pcre.h... no
checking whether pcre.h defines the macros we need... no
configure: error: to build Octave, you must have the PCRE library and header files installed
Any ideas what I'm doing wrong?
